Introduction

Ematics engineers have been involved in design studies and technical proposals for the provision of Station Management Systems and Network Management Systems for underground rail applications.

We can provide fully integrated systems utilising innovative solutions based on state of the art technology for the monitoring and control of station level communications assets, including CCTV, PA/DVA, Help Points and Customer Information Signs.

We can also provide line wide Network Management Systems for the overall monitoring and control of a group of stations on a given line, including the storage and retrieval of historical operational and status information for all associated assets. This is instrumental in providing the end user / infraco with centralised fault reporting, full traceability and Key Performance Indicator data for system operation and system maintenance.
